Title: IC engine transistorised ignition system - has power stage oscillating at natural frequency, energised by several advance stages, for spark generation
Inventor: POSKE FRITZ
IPC: F02P15/10
Filed: 1978-08-18
Abstract: In the ignition coil are generated voltage changes by a power stage energised and controlled by one or several series stages. The voltage changes are utilised for attaining ignition sparks, in conjunction with an ignition coil which are generated during breaking of an interruptor, while being extinguished on its making. Preferably the number of oscillations, and thus the sparks, is controllable per each time unit. Typically the power and series stages, which are transistorised, are separately mounted and connected by a multi-strand cable. The latter may contain a multiple plug connector which can be selectively switched on and off.

Title: Central locking mechanism for furniture sliding drawers - has electric motor for actuating locking rod with rack and pinion mechanism
Inventor: GROENWOLDT ROLF
IPC: E05B47/00
Filed: 1978-08-31
Abstract: The central locking system is used especially for sliding drawers of furniture locked by a common locking bar. The bar can be moved into locking or open position by the cylinder lock. The central locking mechanism ensures the adjustment of locking or open position electrically. The lock triggers an actuating pulse which closes a current circuit of an electric motor (16) whose output pinion (15) engages with a rack (14). The rack moves the coupling slider (9) connected to the rack until the current circuit of the motor is disconnected by limit switches (17, 18). The coupling slider (9) is connected withthe locking bar directly or indirectly.

Title: Crank wound tensometer for perforated paper strip - uses tensile force measuring sheet spring and dial gauges
Inventor: HALLER KARL DR ING
IPC: G01N3/08
Filed: 1978-09-19

Title: Pressure vessel for non-nuclear section of power station - with inner shell for blast effect protection
Inventor: BECKER ERWIN
IPC: G21C13/10
Filed: 1978-10-05
Abstract: Pressure vessel for gaseous media at high pressure, has inside the outer pressure-tight wall, separated by a gap, a thin-walled shell. The shell has qually distributed pressure compensation holes of such size and numbers that the gas is prevented from instant release in case of a burst of the outer wall. This prevents the severe damage which may be caused by the explosive escape of high-pressure gas to safety appliances. Pressure wave and splinter effects are greatly reduced by the presence of the inner shell.

Title: Lubrication system for looper bearings of sewing machine - using short flexible couplings from nearby oil reservoir at same height
Inventor: PAPAJEWSKI REINHOLD
IPC: D05B71/02
Filed: 1979-09-21
Abstract: A lubrication system for the loopers of a double-needle sewing machine, wherein the loopers are mounted on slides by which the distance between the loopers can be adjusted, uses flexible tubing to convey lubricant to the looper bearings from a reservoir which is essentially at the same level as the inlet nipples to the bearings. The lengths and positions of the tubing sections are such that, whatever the position of the slides, the tubes do not contact the machine frame, the slides, or the stitch-forming mechanisms. This arrangement is simpler than previous systems, it eliminates long, ungainly tubes and the need for oil metering devices, and avoids the danger of rupture of the tubes by abrasion.
Patent DE-2942485-A1 (DE)
Title: Ferro-zirconium prodn. by electroslag remelting - of ferrous hollow body contg. mixt. of zirconium oxide and calcium
Inventor: SONNTAG HEINRICH
IPC: C22B9/18
Filed: 1979-10-20
Abstract: Ferrozirconium is produced by mixing zirconium oxide and calcium in stoichiometric proportions, pouring the mixt. into a long hollow iron body and making the filled body an electrode in an electroslag remelting process, using a calcium-contg. slag under an inert atmos., to produce an alloy ingot. The invention provides a simple, low cost method of producing ferrozirconium of any desired iron content, for use as a deoxidant for high quality steels for the aircraft industry. The reaction of zirconium oxide and calcium takes place at the same rate as electrode melting so that melting parameters such as current and voltage are not critical. The reaction mixture forms a plug, just above the melting zone, to prevent uncontrolled entry of the mixture into the slag. Because the iron content of the ferrozirconium product is unimportant, the hollow body can be dimensioned to give optimum remelting conditions. The ferrozirconium is produced in a single step process and can be used directly as a deoxidant.

A vertical vent (10) rises from the tank below the lowest water level (7). It rises above the top of the tank and is open to atmosphere. The water level (13,13') fluctuates more in it than in the tank but gives a smaller surface exposed to atmosphere.

IPC: B29C48/10
Filed: 1980-01-09
Abstract: Composite sheet of foil, intended esp. as a toilet seat cover, comprises at least two layers, one being a thin, water-insoluble sealing layer produced by extrusion of a foil from thermoplastics to produce absolute freedom from pores. The other layer is a water-soluble, thicker support layer. The other side of the support layer may have a textile facing of individual fibres. The sealing layer and support layer are pref. seal-bonded together. By using an extruded foil for the impermeable facing layer, absolute freedom from pores is achieved; by contrast, earlier methods using a solvent with subsequent evaporation led to minute bubbles which form the seats of pores. The support layer is pref. of an alkaline-soluble, low-viscosity block polymer of vinyl acetate with a small content of crotonic acid, esp. containing deposits of soda. The sealing layer is pref. of alkaline-soluble esteric resin of phthalic acid and pentaerythrite.

Title: Erosion- and corrosion-resistant coatings for chemical plant - of natural or synthetic rubber with low rebound elasticity and high hardness
Inventor: KRAUSE ALFRED
IPC: B01J19/02
Filed: 1980-02-26
Abstract: Erosion- and corrosion-resistant coatings for appts. in the chemical and allied industries are comprised of a layer of a natural- or synthetic rubber based coating compsn. having as low as possible a rebound elasticity (DIN 53 512) and as high as possible a Shore A hardness (DIN 53 505). Pref. the rebound elasticity is 40-65% and the Shore A hardness 40-80. Suitable rubbers are e.g. natural rubber, polyisoprene rubber, ethylene-propylene rubber, butyl rubber, polychloroprene, chlorosulphonated polyethylene, fluoroelastomers, nitrile rubber, silicone rubber, SBR, etc. The rubber layer is esp. 0.3-6mm thick, and made by calendering. The calendered sheets may be laminated together or with vulcanised layers to form thicker sheets. The rubber sheets are bonded to the metal surface to be protected in the known way (e.g. VDI guidelines 2537) and vulcanised in situ to form the corrosion resistant layer. The layers have improved resistance to erosion and corrosion under rigorous conditions in chemical plant, and are useful for protecting metal surfaces in pipes, centrifugal pumps, blowers, fans, etc.
